IMPROVEMENT IN BREAST-PINS.

The Schedule referred to' in these Letters Patent and making part -of the 'samag' To all whom it may concern:

Be it known that I, THEoDoR G. EISWALD, of the city and county of Providence, in the State of Rhode Island, have invented a certain new and usel`ul llmprovement in Breast-Pins, and other similar artic es.

My invention consists in a novel mode ot' mounting the pin-tongue, and in the form of 'the' catch or hook; and I do hereby declare that the following specificati'on, taken in connection with the drawing furnished aud'forming a part of the same,is atrue, clear, andexact description of the same.

Figurell represents the back of abreast-pin, having my improvements thereon.

Figure2 represents the same, 1n longitudinal section. '1-

.A is the body ot' the p'in.

B is the pin-tongue. It is provided with a spherical hzad, firmly set. Its opposite end is pointed, as usua C, isV a spherical socket, withits interior slightly larger than the head of the pin-tongue. In the side of this socket is a; slot extending from a point near its top to the bottom, having a' width slightly greater tharil the thickness of the wire of which the tongue is ma e.

D isthe catch or hook. It may properly be denominated a compound catch.n It consists, ,ot a piece of wire, of suitable size and quality, having its two ends bent vtoward each other in inverted scrolls. This catch ,isfsoldered to the back of the p'n in the usual manner, at' right anglesfto the line of -the pin-tongue. The two'inner edges ot the catches are closely in contact,

between the two edges into the open space below. To

and, tosecure the piu, it is necessary to force it down `disengage it, th'e 'same .degree of force is requisite, rendering it, in fact, a safety-catch.

In the use ofthe hinge-joint and the ordinary hook, as generally used', it is essential that ablock be placed ou the back of the vbreast-pin, near the hinge-joint, to secure a springy bend to thefpin, and keep it in proper engagement with the hook or catch. Itis this constant strain upon the' joint, and frequent bending of.

the pin-tongue, that occasions such general breakage ofthe pins and joints. With my compound hook no strain is required on the pin-tongue to keep it in placa,r

Inusing the ordinary hook ou breast-pins, which can'be'worn .'in any position, it is found.l diicult to maintain a. proper relation between it andthe pintongue, except the pin be always worn with the opening in the hook facing downward. With'my catch the Ipin is 'held iirnily therein, regardless of the positiouof lation with each other,substantially as shown and described, in combination with the tongue of a breastpin, ear-ring, or other similar article. `Witnesse s:' vITHFIODOR G. EISWALD.
